US Patent 11855241 LED device having blue photoluminescent material and red/green quantum dots

A light-emitting device includes a plurality of light-emitting diodes, a first cured composition over a first subset of the light-emitting diodes, and a second cured composition over a second subset of light-emitting diodes. The first cured composition includes a first photopolymer and a blue photoluminescent material that is an organic, organometallic, or polymeric material, embedded in the first photopolymer. The second cured composition includes a second photopolymer and a nanomaterial embedded in the second photopolymer. The nanomaterial is selected to emit red or green light in response.
